VEHICLE SPRING SUSPENSION.

Specification of Letters Patent.

Pateutedltlay 21, 1918.

lpplication filed November 10, 1917. Serial No. 201.314.

To all whom it may; concern:

Be it known that I. JAMES TREANOR, a citizen of the United States, and a resident of the city of New York, borough of Man hattan. in the county and State of New York. hav invented a new and Improved Vehicle Spring following is a full. clear, and exact descrip tion.

The invention relates to automobiles and other vehicles, and its object is to provide a new and improved vehicle spring, suspension arranged to minimize jolts and jars incident to the vehicle traveling over uneven or rough portions of the roadway thus insurint easy riding by the occupants seated in the vehicle l)Oti Another ohject is to permit the use of (Ulllllill'tltl\(l}' light springs.

in order to accomplish the desired result; Hais made of connected levers t'nlerumed on the vehicle hotly. one of the levers bein}: connected with the axle. and a spring v upported on the \lhltlo hodv and engaged by another of the said levers.

practical eiolmdinicnt ol' the invention is represented in the accompan vin; drawin; forming a part of this specification, in which similar characters ol' reference. indicate correspmuliug' parts in both views.

l igure 1 i a sectional side elevation of the vehicle spring suspcn iou as applied, the section being on the line l----l of Fig. 2; and

Fig. 2 is a plan view of the same.

The vehicle laid H1 i providcd with depending hrachcts II and i2 spaced apart. for the tree passage of the axle 13 provided with the usual vehicle wheels 14. The l'u'ackets ti and 1; support depending: rods to and ill extending through a plate 17 engzaging the under itlt' ol' the axle. 1 and the lower endsof the said rods and Ill are provided with cups lh and lit on which rest springs il and :!l resting at; their upper ends in cups 12:. 23 abutting: against the under ide of the plate l7. ()n I he lower-ends of the rods 15 and ill vscrew nuts ill. 25 to hold the cups t and it! in larc and to allow of adjusting the said Hops up or down with a view to increase or decrease the tension of the springs '10 and :fl'. Hy the arraugw nu-nt. desrrihcd the vehicle hotly :ltltis spring supported on the axle Ill.

The top ill) of the axle is slightl rounded oil and on the top rests the Frec end ol a lover Ill l'ulcruincd at. its other end at, 32

Suspension, of which theon the vehicle body 10. The ever 31 is pivotally connected adjacent its co tact; with the axle 13 by a link 33 with a 5 gift arm 34 of a lever 35 fulcrumed at; 36 on the hracket 11. The lever 35 is provided with a long arm 37 resting at its free end on a spring 40 mounted on a support 41 fulcrinned at it! on the vehicle body 10. The support 41 is provided with a guideway iii for the outer end of the arm 37, and a pin 44 extends through the outer end of the arm 37 and sliclahly engages a slot 45 formed in the ,euideway 43. By the arrangement described a compound lever mechanism is provided hetween the axle 13 anti the main spring 40 mounted on the vehicle body 10. and by the use of this'compound lever mechanism the main spring-40 may he made comparatively light thus dispensing with the heavy and cumbersome springs now generally employedfor supporting the vehicle body from the axle 13.

T1 is understood that the spring 40 is. however. stronger than the springs 20 and 21 which take up the rebounds. Heavy jolts and jars are taken up by the compound lever mechanism and the spring, 4O owing to the axle 13 acting: on the short end'of the lever 31 which by its link 33 is connected with the short arm 34 of the lever 35.

It is understood that a comparatively short swinging motion given to the lever 31 hr the axle 13 causes the long arm 37 of the lever 35 to swing;' a coni nlrat'ively long: distance than corresimndingly (10mincssing; the spring 40.

Having thus descrihed my invention, I rlaiin as new and desire to secur' by Letters Patent 1. vehicle suspension. comprising. a lever. of which one end is fulcrunied on the vehicle hotly and its other end engages the axle of the vehicle. a second lever fulerumed on the vehicle body at; a point hetwten its ends. a link connecting one end of the said second lever with the said first-named level at a point het ween the ends of the said first-minted lever, and a spring supported on the vehicle l|()tl and engaged by the other end of the said second lever.

52. vehicle suspension. comprising a lever l'ulcruincd at one end on the vehicle hotly and engaging with its free end a. V6 liiclc axle, a second leverfulcrutntktlnear 0H6 end on the vehicle body and hming a short arm and a long arm, a link connecting the leis short arm of the said second lever with the said first-named levee at a point adjacent the axle, and a spring supported on the vehicle body and engaged by the terminal of the long arm of the second lever.

3. In a vehicle s ring sus ension, Lhe combination of an. ax e, a car Jody, a light rebound spring device connecting the car body directly W ith the axle, a leverfulerumed at W one end on the said car body and resting JAMES 'l, REANOR.
